[GitHub] [iceberg] kbendick opened a new issue #4007: Document `max_concurrent_deletes` parameter for the Spark procedures `remove_orphan_files` and `expire_snapshots`
kbendick opened a new issue #4007:
URL: https://github.com/apache/iceberg/issues/4007
As of Iceberg 0.13.0, the Spark stored procedures `remove_orphan_files` and `expire_snapshots` both support controlling the parallelism of deletes via a parameter `max_concurrent_deletes`.
By default, without this, the files of each action are deleted serially in the current thread.
This parameter is used to instantiate a thread pool of the given size, which is passed to the method `executeDeleteWith(ExecutorService executorService)`, causing the deletes to take place in a work thread pool.
Without using this, the file deletes can take significantly longer and we should add documentation for them.
